Selecting options for your RAID set
To optimize storage performance of a RAID set, you can set the storage block size used by the disks in the set to match the size of data stored on the set. You should select these options at the time you create a RAID set.
For example, a database might store small units of data so a small block size might be best for the RAID set. A video processing application might require fast throughput of large amounts of data, so a larger block size might be best for the set.
You can also set up a mirrored RAID set to automatically rebuild the set in the event of lost or damaged data. Choosing this option also allows you to easily add additional or "spare" hard disks to your mirrored set as replacements.
- When you're creating the RAID set, click the Options button.
- Choose a block size for the RAID set from the RAID Block Size pop-up menu.
- If you are creating a mirrored RAID set, select the "RAID Mirror AutoRebuild" checkbox.
- Click OK.
